Tom qabSMT reflow solderingpeb yuav ntsib qee qhov tshwm sim tsis xws luag, cov SMT ua cov khoom tsis xws luag yuav cuam tshuam ncaj qha lossis cuam tshuam rau qhov zoo ntawm cov khoom.Cov xwm txheej tsis zoo no yog qhov tseeb SMT cov tswv lag luam ntawm thaj chaw ua haujlwm tsis raug txiav txim siab, txhawm rau muab cov qauv kev lag luam rau kev txhim kho kev tsim khoom thiab kev ua haujlwm ntawm lub npe phem.Nyob rau hauv qhov tseeb thaj ua rau cov phenomena tsis xws luag, yuav tsum nruj me ntsis rework los yog kho kho.Yog li peb yuav tsum nkag siab li cas los txiav txim qhov tshwm sim tsis zoo?
Hauv qab no rau koj los txheeb xyuas cov hauv qab no:
1. (txawm tias tin) SMT ua vuam txawm tias tin tseem hu ua tin choj, nruab nrab ntawm cov khoom kawg, nruab nrab ntawm cov pob qij txha uas nyob ib sab ntawm cov khoom, nrog rau cov pob qij txha thiab cov xov hlau uas nyob ib sab, perforations, thiab lwm yam. lub solder txuas ua ke, SMT ua kev lag luam hu ua txawm tin.
2. (monument) tombstone, tseem hu ua Manhattan phenomenon, hais txog ob qhov kawg ntawm cov khoom siv chip, tom qab reflow soldering, ib qho ntawm cov soldering kawg deb ntawm lub ncoo nto ntawm tag nrho cov khoom yog oblique thiab upright.SMT kev lag luam hu ua monument.
3. (sab sawv ntsug) nti tivthaiv sab thiab PCB ncoo tiv tauj tshwm sim.SMT kev lag luam hu ua sab sawv.
4. (offset) cov khoom nyob rau hauv txoj hauj lwm kab rov tav txav mus, uas ua rau lub solder kawg lossis tus pin tsis txuas rau PCB ncoo.
5. (anti-dawb) piece ntawm tivthaiv pem hauv ntej mus rau lub PCB, nyob rau hauv qab sab li phenomenon.
6. (tin hlaws dai) nyob rau hauv lub reflow soldering, txuas mus rau ib feem ntawm cov khoom sab los yog tawg nyob rau hauv lub solder pob qij txha annex me me hlaws ntawm solder.
7. (txias soldering) reflow tsis tiav phenomenon, lub solder tsis ncav cuag nws melting point kub los yog vuam kub tsis txaus, yog li ntawd nws yog solidified ua ntej lub wetting thiab ntws, tsis muaj tsim ntawm tej hlau alloy txheej, yog li ntawd tag nrho cov. los yog ib feem ntawm lub solder nyob rau hauv lub xeev uas tsis yog-crystalline thiab tsuas yog tsim nyob rau saum npoo ntawm cov hlau yog soldered.
8. (tub ntxhais suction) solder los ntawm lub ncoo raws tus pin kom nce mus rau tus pin thiab nti lub cev, uas ua rau cov solder tsis txaus los yog khoob khoob ntawm cov pob qij txha.
9. (rov qab) yog hais txog lub polarity ntawm cov khoom tom qab vuam, lub polarity ntawm cov kev taw qhia ntawm cov kev xav tau tiag tiag ntawm cov kev taw qhia tsis zoo ib yam.
10. (npuas) solder nyob rau hauv lub solidification ntawm cov roj ua ntej tsis ua hauj lwm kom khiav tawm nyob rau hauv lub sij hawm, lub tsim ntawm hollow phenomenon nyob rau hauv lub solder sib koom.
11. (pinhole) nyob rau hauv qhov sib koom ua ke saum npoo los tsim cov koob zoo li qhov.
12. (fissure) solder pob qij txha vim cov neeg kho tshuab kev nyuaj siab los yog kev ntxhov siab nyob rau hauv lub phenomenon tshwm sim ntawm tawg solder pob qij txha.
13. (tin tip) welding ntawm sab nraud protruding koob zoo li los yog spiky tin.
14. (ntau tin) soldering ntawm lub solder yog ntau tshaj li qhov ib txwm xav tau, yog li ntawd nws yog ib qho nyuaj rau pom cov txheej txheem ntawm soldered qhov chaw los yog solder los ua ib pawg ntawm spherical.
15. (qhib solder) tivthaiv pins / solder kawg ntawm tag nrho cov tawm los yog deb ntawm lawv cov ntaub qhwv, thiab tsis yog vim soldering.
16. (dawb me ntsis) tshwm nyob rau hauv lub laminated substrate nyob rau hauv ib tug tshwm sim, nyob rau hauv uas cov iav fibers nyob rau hauv lub longitudinal thiab transverse crossings thiab resin sib cais.Qhov tshwm sim no tshwm sim raws li qhov tsis sib xws ntawm cov pob dawb los yog lub substrate nto nyob rau hauv "cross-shaped", feem ntau cuam tshuam nrog kev tsim kev ntxhov siab vim yog cua sov.
17. (grey welding) vim qhov kub thiab txias ntawm vuam, ntau dhau ntawm cov evaporation thiab rov vuam, thiab lwm yam., qhov saum npoo ntawm cov vuam yog grey, cov khoom siv lead ua xoob xoob, ntxeem tau thiab slag-zoo li.
Zhejiang NeoDen Technology Co., LTD., nrhiav tau nyob rau hauv 2010, yog ib tug kws chaw tsim tshuaj paus tshwj xeeb nyob rau hauv SMT xaiv thiab qhov chaw tshuab, reflow cub, stencil printing tshuab, SMT ntau lawm kab thiab lwm yam SMT khoom.Peb muaj peb tus kheej R & D pab neeg thiab tus kheej lub Hoobkas, ua kom zoo dua ntawm peb tus kheej nplua nuj kev paub R & D, kev cob qhia zoo, tau txais lub koob npe nrov los ntawm cov neeg siv khoom thoob ntiaj teb.
Peb nyob hauv txoj haujlwm zoo tsis yog tsuas yog muab koj lub tshuab zoo pnp, tab sis kuj yog qhov kev pabcuam zoo tom qab muag.
Cov kws tshaj lij engineers tau kawm zoo yuav muab kev txhawb nqa rau koj.
10 engineers muaj zog pab neeg tom qab kev muag khoom tuaj yeem teb cov lus nug thiab cov lus nug hauv 8 teev.
Cov kev daws teeb meem muaj peev xwm muab tau hauv 24 teev ob hnub ua haujlwm thiab hnub so.
